This was the extension that made Thunderbird. Quick and streamlined message filing is a primary use-case that I would expect to come out of the box.
However, it doesn't, and Nostalgy seems to no longer be supported. I would thus recommend finding other e-mail alternatives...
I'm the original author of Nostalgy, and I have recently started using Quick Folder Move, which is enough for my own needs. You should try it out!
